A good average density for topsoil is 100 pounds per cubic foot. There are 27 cubic feet in one cubic yard, and so one cubic yard weighs around 2,700 pounds.
2,700/40 = 67.5
Therefore, it will take about 67.5 forty pound bags to make one cubic yard of topsoil.
A person weighing 180 pounds on Earth would weigh 30 pounds on the moon.
It would depend on what you are measuring. A cubic yard of mulch is lighter than a cubic yard of gravel.
A person weighing 150 pounds on earth would weigh 137 pounds on Venus
A kilogram is equals to 2.20462 pounds. An object weighing 55.8kg would weigh 123lbs.
180/62.5 = 2.88 cubic feet
6,666,666,666 people weighing an average of 150 pounds each would weigh a total of 1 trillion (1,000,000,000,000) pounds.
The answer depends on the density of the rock. A cubic foot of pumice, for example, can have a mass of around 15.6 pounds whereas minerals rich in metals such as iridium will have mass exceeding 1200 pounds.
forty-nine pounds
A cubic inch of lead is about 0.4 pounds. So 10 pounds would be about 25 cubic inches which would make a ball about 3.6 inches in diameter. That is slightly larger than a softball.
Weighing 104 pounds at 5'5, that would give you a BMI of 17.3.
